Question

Solve the equation for x by graphing

Answer 1

Graph each side of the equation and the solution is what the x-value is at the point of intersection. In this case is about -1.25.

Answer 2

-1.25.

Explanation:

Given :
`-4x-1 = 5^x+4`

To Find: Solve the equation for x by graphing

Solution:

`y=-4x-1`

`y= 5^x+4`

Plot the graphs

The intersection point of these two equations will give the value of x.

So,
`y=-4x-1` -- green line

`y= 5^x+4` -- purple line

Intersection point : (-1.282,4.127)

So, x = - 1.282 ≈ -1.25

The value of x is -1.25.
